1 Operating nstructions & Parts Manual CART-2000 Please read and save these instructions. Read carefully before attempting to assemble, install, operate or maintain the product described. Protect yourself and others by observing all safety information. Failure to comply with instructions could result in personal injury and/or property damage! Retain instructions for future reference. Hydraulic Elevating Carts CART-2000 & CART-4000 Description Portable ergonomic elevating carts minimize worker bending and lifting. Materials can be easily loaded onto platform of cart, lowered to safe transporting height, and raised to unload at destination. Moves easily on four polyurethane caster; two swivel with brake and two rigid. All models feature a down speed control valve, internal hydraulic velocity fuse in each cylinder and an exclusive automatic two-speed manual hydraulic foot pump. All steel construction. Powder coated red finish. Failure to follow the proper operating instructions could result in iajury. After receiving a hydraulic elevating cart, visually inspect the frame components and hydraulic unit for damage. f damage is evident, notify delivering carrier immediately and file necessary claims. S Tcations and Dimensions General Safety nformation 1. Not a personnel lift. Keep clear when operating. 2. Never go under platform if there is weight on the unit. 3. Remove weight before working on unit. 4. Use only maintenance parts supplied or approved by the manufacturer. 5. Do not change pressure relief valve setting. 6. Do not clamp cylinder in a vise as you may distort barrel. 7. Never operate lift unless you are watching it. 8. Load lift as uniformly as possible. 9. Consult factory for uneven loading. 10. Do not continue to pump if unit is not raising. 11. Relieve system pressure by slowly operating pressure release mechanism. 12. Consult factory if any modifications are going to be made Do not use brake fluids or jack oils. Use AW-32 or hydraulic oils. Assembly TOOLS REQURED: (2) 9/16 in box end wrenches After unpacking the cart locate the handle and the hardware to install it. Line up the mounting holes on the handle with the holes in the frame and install and tighten the bolts. Your cart is now ready for use.

2 Hydraulic Scissor Lift Carts Foot Pump Operation Your new lift equipment has been supplied with our exclusive 2-speed foot pump. The initial features of your pump includes a primary pressure relief, pressure compensated return flow control valve, and an integrated lowering valve. Replaceable bushings, valve components, and seals have been utilized in the construction of the pump in the event that replacements are necessary. Stay clear of moving parts. The platform will rise as the foot pedal is pumped. Depressing the lowering valve will lower the table at a controlled rate of descent. n the event the platform has been overloaded, the pressure relief will open because of excessive pressure buildup in the hydraulic system. Oil will bypass into the reservoir. NEVER change the pressure relief setting. DO NOT exceed the rated capacity of your lift equipment. SPEED SELECTON FOR TWO-SPEED PUMPS This pump offers two "speeds".'the low speed setting produces low volume/high pressure. The high speed setting produces high volume/low pressure. The operator has the option of selecting the optimum pump speed for the application at hand. Pump speeds are selected by sliding the "lock collar" (See below) in or out. An occasional drop of oil will keep the collar working freely. AR BLEED PROCEDURE Whether your pump is a new installation, or has been recently serviced, air has likely entered the hydraulic system. The design of this pump includes an "air bleed screw" which will aid in the removal of unwanted air from the foot pump area of hydraulic system. Use the following steps to remove this air from the system. 1. Check all fittings to be sure they are tight. Ensure that the oil is filled to within 1" of the top of the reservoir when the lift is in the fully lowered position. 2. Locate the "air bleed screw" (see figure 3} and loosen approximately 1/2 turn counterclockwise. As soon as you have loosened the screw, slowly depress the foot pedal. This will force the air out of the pump chamber. Before you let the pump pedal return to the "up" or "home" position, tighten the air bleed screw. This will prevent air from reentering the pump chamber. Repeat the above procedure until the pump chamber is completely filled with oil and a "spongy" feel is no longer present. f the air bleeding procedure has been successful, the feel the of the pump pedal will be firm and the complete stroke of the pump will produce fluid flow. LOAD COLLAR LOWERNG VALVE PRESSURE RELEF VALVE Maintenance Al bushings and bearings are of the pre-lubricated type and will last for a long period of time without additional lubrication. Tb increase bearing life, it is recommended that a few drops of light machine oil be applied at each pivot point every 6 to 12 months. DALY Visually check and do not use if any of the following are visible: 1. Oil Leaks. 2. Structural deformation of legs or frame. 3. Unusual noise or binding 4. Check casters for proper operation. MONTHLY Hydraulic foot pump 1. Check for oil leaks. 2. Check clevis and pivot points for wear. 3. Check rollers for looseness and wear. 4. Check for unusual noise. 5. Make sure all warning labels are in place and in good condition. 6. Clean off dirt and debris. OUTLET CHECK VALVE FLOW CONTROL VALVE 2

3 Maintenance procedures YEARLY Hydraulic oil should be changed at least once a year, or sooner if the oil darkens or becomes gritty. Flush reservoir before refilling. Presence of water is indicated if the oi turns milky. Recommended oil: AW-32 hydraulic fluid or equal. All maintenance work must be preformed by qualified personnel with training in the repair of electrical and hydraulic components. NOTE: f hydraulic oil is milky white in color, water is in the hydraulic system. Change the hydraulic oil immediately. TO FLL UNT WTH OL 1. Raise the platform and block the leg assembly in the fully raised position. 2. Remove the upper cylinder pin. 3. Loosen the set screw in the lowering rod linkage. 4. Release the lowering valve. 5. Collapse the cylinder rod back inside the cylinder. 6. Remove the oil fill plug. 7. With the cylinder horizontal, fill with AW-32 grade hydraulic oil (or equivalent). 8. Reinstall the fill plug, and then reinstall the cylinder. TO BLEED SYSTEM 1. Ensure platform is in lowered position. 2. Operate the lowering mechanism and pump the foot control several times slowly. TO FLL WTH OL LOW OL CONDTON 1. Raise the unit as far as it will go. 2. Remove the oil fill plug. 3. Add oil 1 oz. at a time. 4. Pump the foot control. 5. Repeat steps 3 and 4 until the unit's maximum height is achieved. 6. Once the maximum height is reached, add 1 oz. of oil and reinstall the fill plug. F CART LEAKS DOWN 1. Completely lower the platform. By hand, grasp the deck at the hinge end of the leg assembly. Raise the deck as high as possible, then carefully, while standing aside, allow the assembly to drop. This procedure draws oil through the load holding check valve and "washes" debris (if present) from the ball and seat of the device. t may be necessary to repeat this procedure a couple of times to remove all debris from the check valve thus, eliminating table drift. 2. Check the oil level in the pump assembly. The oil should be level with the bottom of the hole with the scissor legs in the lowered position. (Deck tilts up). NOTE: f these steps fail to return the unit to service, contact supplier for further instructions. Fill Hole 3
